A Mechanics Model and Active Control for Smart Constrained Layer Damping Structure

  The active vibration control of beam is researched by using piezoelectric constrained damping structure.The energy characteristic of each layer for the piezoelectric smart constrained damping beam is completely expressed based on the finite element method and the damping layer shearing movement relationship is described by ADF model.Then the structure mechanics model for dynamic parameters is established.Applying displacement error signal,an adaptive filter controller is designed.Under the different outside disturbances,structure vibration responses with active control are analyzed.It shows that the piezoelectric smart constrained damping structure can have good control performance for the active and it has a good engineering prospect.
